There is indeed a chance to become a full member, and different people have different opportunities to become a full member. For example, the postal service has recruited students from a school, and students from that school can become full members as long as they stay in it for 1 to 2 years. The purpose of recruiting students in other schools is to see your performance and interpersonal relationships. The quota is limited. Postal employees are divided into three categories: A\B\C B \ C. They just entered C, and then gradually rose. I know a person who has been a postmaster for more than ten years and has not even been promoted to B. One of the important reasons is that her superiors don't like her. She is very capable, but unfortunately. . . . . . Of course, some of them were promoted within a few years. So look at people. A\B\C The wages of workers are low. Of course, the higher the level, the better. Hope to adopt.
